Recent Bratislava group results on Midrapidity antiproton to proton ratio in p-p collisions

ALICE Collaboration : Midrapidity Antiproton-to-Proton Ratio in pp Collisions at √s=0.9 and 7 TeV Measured by the ALICE Experiment; Phys. Rev. Lett. 105, 072002 (2010)

• Results at 900 GeV show small excess of baryons over antibaryons

• At 7 TeV mid rapidity ratio goes to unity

• Results are well described with BN transfer via Regge trajectory using α≈1/2

• No significant contribution with constant BN transport with α≈1 is needed

Representatives in XFEL organs

~20 people involved in research on 2nd, 3rd and 4th (free electron laser) photon sources.

~200 people participated in training (popularization) courses with main topic: X-ray light sources and their applications.

Activities towards the European XFEL

- to join leading international research groups, be part of the collaborations, propose and perform experiments at the XFEL.

- transfer of the FEL knowledge and technologies to Slovak scientific groups at universities and research institutions with aim to involve them to different areas of R&D needed for this technology. Be involved in User consortia, shaping the end experimental stations of the XFEL.

Students and young physicists at CERN and in European laboratories

A grant scheme of the Ministry of education allowed 14 students and young physicists stay at CERN 1/2 year in 2009

In 2010 the program was enlarged to European research laboratories in framework of ESFRI – 35 students spent in Euro Labs ½ of the year, from this 24 at CERN

The program at CERN was highly effective - students and young physicists worked with top class supervisors, obtain a lot of knowledge and produced interesting results useful also for CERN collaborations

Slovak Committee for cooperation with CERN appreciate this scheme and supports its prolongation and enlargement to more students and more laboratories

Conclusion

Main task for Slovak HEP community given by previous RECFA session in Slovakia in 2004 was to improve conditions and involvement of students and young physicists.

We consider, that we fulfill this goal with long term stages at CERN and other EU Labs. Work of students and young physicists at CERN was highly effective and useful. The scheme should continue in the future.

This measure enlarged the number of Slovak CERN users form 55 in 2004 to 80 in 2011, from which majority are young people.

Important step forward to higher involvement of Slovak physicists in European Labs. is signing the MoU with XFEL, where Slovakia is a member state. Slovakia also signed MoI with FAIR. We hope, that Slovakia will participate on FAIR as a full member.
